Method for preparing polyesters having intrachain free acid functions |
| 摘要 |
The invention relates to a method for preparing polyesters A containing several mid-chain free acid functions by ring-opening polymerisation in the presence of a chain initiator: the benzyl diester of the tartaric acid, the phenyl radical of which is optionally substituted. A: aliphatic based on cyclic esters such as lactides and glycolides.
